General knowledge of paint: spray or roll coating process should be adopted in latex paint construction

Core tip: in the process of home decoration, many owners often hesitate to use emulsion paint on the wall, do not know whether the spray effect is good or roll coating effect is good In fact, the two kinds of construction technology have advantages and disadvantages A coating method in which spray is applied to the surface of the object to be coated by means of a spray gun or disc atomizer and by means of pressure or centrifugal force to disperse into uniform and fine droplets It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as large flow low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc Spraying has excellent surface quality Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: in the process of home decoration, many owners often hesitate to use emulsion paint on the wall, do not know whether the spray effect is good or roll coating effect is good In fact, the two kinds of construction technology have advantages and disadvantages A coating method in which spray is applied to the surface of the object to be coated by means of a spray gun or disc atomizer and by means of pressure or centrifugal force to disperse into uniform and fine droplets It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as large flow low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc Spraying has excellent surface quality The coating sprayed on the wall forms a smooth and dense coating without brush marks, which is incomparable with brush and roller Moreover, the coating efficiency is high The spraying efficiency of single operation is as high as 300-500 square meters per hour, which is 10-15 times of that of manual brushing Spraying is the best way to paint some corners and gaps But how wasteful spraying materials are Secondly, it is easy to cause mutual pollution when spraying with various colors At last, the paint surface is too thin to be repaired once bumped, but it can only be repaired with professional spraying equipment, which costs too much The type and quality of roller will directly affect the final effect Roller coating is easy to appear uneven roller marks Some people don't like the trace, but some people like the concave convex feeling of the roller However, if the color is not well mastered, it is easy to have flower marks, and the visual effect is not good The best choice is a high quality short hair roller Roll coating needs to control the mixing proportion Otherwise, good paint will not work Roll coating can test the technology of decoration master very much, and it also requires high brushing tools The decorator in charge of the rolling coating process must have rich construction experience, and pay attention to the water mixing quantity and painting strength, otherwise the construction effect will be affected Brush painting with brush or wool brush is larger than roll painting, but the paint film is thin, and the covering layer of each time is worse The connection of brush painting is also easy to see, especially the glossy emulsion paint Because the brush is relatively soft, it is not easy to construct if it is too thick, so the amount of water added is too large, which is the main reason why the film effect is worse than roll coating Brush marks will be produced There are advantages and disadvantages in each of the two construction processes The owner can choose according to the actual situation For the general household, roll coating is more used, which can save 30% material compared with spraying If the wall area to be painted is large, spraying can be selected, so the construction quality will be more guaranteed Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
